Test & Measurement

Turns Counter is used to test transformers.

Model HBC-2 Turns Counter counts turns of magnet wire in transformers, measures turns ratios between primary and secondary windings, and detects presence of shorted turns. Range selector of 1:1 or 1:2 ratio allows count of up to 1,999 or 3,998 turns respectively, and test frequency of 2.5, 12.5, or 50 kHz can be selected, depending on core material. Transformers up to 15 lb can be placed on...

Materials

C-Cores come in 32 sizes ranging from 5 VA to 5 kVA.

Made from M5 silicon steel, C-Cores are suitable for single-phase transformers with single coils, both single loop and double loop, as well as double coil and double loop. They can be bobbin-wound and require no assembly or stacking of laminations. Rectangular tubes of phenolic or laminated paper required for winding cores are available for all sizes.

Flat Magnet Wire includes sizes from 30 to 9 AWG.
Electrical Equipment & Systems

Flat Magnet Wire includes sizes from 30 to 9 AWG.

Flat Magnet Wire is produced from round pre-insulated magnet wire that is flattened between mirror polished work surfaces. Insulation is stressed in only one direction, and resistance and wire gauge remain largely unchanged. Wire comes in 10 or 20 lb spools and 5 ratios of thickness to width. User can select cross sectional area in sq mm or sq mil, or in terms of wire resistance. Insulation is...

Power Transformer Core has circular cross section.
Materials

Power Transformer Core has circular cross section.

O-Core uses silicon steel strip, gradually pointed towards end. Transformers wound on O-cores are 15% smaller in size and weight than toroidal transformers. Available with power ratings from 20 to 1200 VA, 50-60 Hz operation, O-cores use grain-oriented silicon steel. With fully rounded edges, transformer does not require epoxy fluidizing or injection molded core jackets, and can be insulated by...

Power Supply reduces common mode noise by 60dB.

Built around balanced and shielded isolation transformer design, Model BP30 balanced symmetrical isolation power supply eliminates noise from unbalanced AC power lines. There are 4 duplex grounded receptacles providing 8 separate outlets and one 15 A time-delay fuse. Transformer uses toroidal core construction, and includes static shield between primary and secondary windings. Maximum power is...
